Xorg log

The hyperspace demo from rss-glx (Really Slick Screensavers) causes an immediate hang in X.

Killing hyperspace does not help and the hardware is wedged upon killing Xorg.

Backtrace from Xorg

reproduced on g45.  Noted that the app only sets s/t wrap modes on cube mapping, but the docs claim that we need to have all 3 in the same mode or it gets angry.  Smashing all 3 settings to CLAMP didn't help, though.  The hang is on what is, at first glance, a perfectly healthy batchbuffer. (INTEL_DEBUG=bat,sync)

I have a very similar issue on a box with a GA-EG45M-DS2H (G45) motherboard. The backtrace I see in xorg is different though and I also don't have any "[mi] EQ overflow" spam in my xorg.log. Once there is a patch for this, please post the commit sha1 or .patch and I will test it on my box as well.

My bug is here:

I can no longer reproduce this with Mesa master.  Can anyone else test?
Comment 7 martin 2009-03-06 11:07:30 UTC
If would be useful to understand when this got fixed (for potential cherry picking), I might try to bisect later (if I find the time) but if anyone got known good or known bad commits, please paste them here.

I just tried Mesa 2305642b2e8edcebdc727f1181f7dbfcc78e8028 and it no longer causes a hang.

Mass version move, cvs -> git
